The QuickSilver Sport System with Sound Architect Valves gives your Defender P400 the sound you expected from the factory.
Loud or Quiet - our system uses our revolutionary Sound Architect™ Module, which is controlled by your mobile phone via the QuickSilver App. It could not be easier.
With the valves shut the QuickSilver system provides a civilised note which is unobtrusive and perfect for long journeys and early starts.


Switch to valves open and the monstrous side comes alive with volume and pitch increased to deliver a pure inline six car sound that enriches the experience.
Furthermore, in dynamic driving mode on occasion the exhaust delivers wonderful pops on the up-change & overrun, a nice touch.


The QuickSilver system is truly plug & play, it requires no intrusion into the cars's OE systems and is completely reversible if ever required.  

Key Features:

  • Valve control for the perfect sound.
  • Stainless Steel mandrel bent tubing.
  • Improved throttle response.
  • Fantastic burbles and pops on the overrun.
  • Civilised to sports car in an instant.
  • The 4x straight carbon fibre tail pipes and mirrored traverse box are a huge improvement to the rear view.

Aggressive chewer who loves fetch approved!!
Size: Medium, Size: Medium
I highly recommend the Chuck-It brand in general, especially for dogs with an aggressive bite. These balls are awesome and are the most durable balls I’ve bought for my 50 lbs lab mix. He has not been able to break one of them yet and we’ve had a few of the squeaky balls for months. They are a bit pricey but worth it. The one in the pic has been used for months, lives outside and you can see it’s still in great shape.

Good quality dog ball for playing fetch
Size: Medium
My dog and family love these chuck it balls to play fetch with our dog. They are durable and fun. They squeak which is added fun for any dog! Regular tennis balls my dog chews apart and they get pretty gross after playing and being left outside. These can be easily washed off and cleaned. These balls last! Would recommend to anyone with a dog and would purchase again.

Colorful, Sturdy & Great Value
Color: Large Set of 4
Purchased for our two puppies when they were 2 months old and weighed about 14 pounds so theses balls were a little big for them to hold in their mouths but that didn't stop them from trying. While they did like these balls they much preferred softer soccer balls, the later of which did not hold up well at all. I had hoped they would play with these balls more when they were older but that hasn't happened 5 months later. I guess it's no fun if you can't tear the toy apart. Colors are very bright and they do enjoy chasing after them as long as I am the one rolling them across the room for them. Maybe when they progress to batting things with their paws they will start to do this for themselves.
